Etymology

Hammond and Scull think that Nob was perhaps chosen rhyme with Bob, and that it does not appear to be recognized diminutive or nickname.[7] It is also possible that Nob was a nickname of a person named Robert; Tolkien's review of M. Förster's Die Französierung des englischen Personennamenschatzes mentions the name Nob in one line with better known names as Hob and Rob.[8]

Portrayal in adaptations

Because of his minimal role, Nob is usually left out of adaptations. He had a better fate than his co-worker Bob, though, who has yet to make an appearance.
